Whilst these fossils were being examined, G. PHILLIPS Bevan, Esq., said 

 that, in spite of the rules of the Woolhope Club, he must crave permission to 

 thank the members for their great kindness in electing him an honorary member. 

 He did so very sincerely, for he thought it an honour, and was very pleased to 

 belong stiU in this way to the club. After all he had not gone so very far off. 

 He hoped to remain at Cheltenham, and he could only say that it would give 

 him great pleasure at any time when he was able, to render any sei-vice to the 

 club (applause). 



NEW MICROSCOPIC LAMP. 



Edmund Beown, Esq., of Mountain Ash, then exhibited Collins 

 Microscopic Lamp. It was just brought out, he said, and as he could testify 

 was a most useful lamp, far surpassing any he had seen before. It was made 

 with Fiddian's metallic lamp shade and chimney, and, indeed, its great novelty 

 consisted in its skilful adaptation to this invention. He had found its great 

 advantages to be — 



1st. That it thi-owa its light solely on the object to be examined. 

 2nd. That being made of copper it acts as a perfect shade, and protects 

 the eye from all extraneous light. 



3rd. Being coated internally with a wash of plaster of Paris, it emits an 

 intense wMte light imitating closely the white cloud Ulumination so prized by 

 microscopists ; and 4th, being metallic and not liable to break there is a great 

 saving in the expense of glass chimneys. 



He had no hesitation in saying from his experience with it that with these 

 qualities the lamp and shade is as good as can be made for perfect vision with 

 the microscope and a very great boon to all microscopists. To medical men 

 using the opthalmoscope and laryngoscope he could strongly recommend it as 

 a most useful illuminator, since only the ray of light coming from the lamp could 

 enter the eye or throat. He ought to add, the whole cost of a perfect lamp 

 with proper adjustments and reflector was 30s. ; the shade alone, which could 

 be fitted to any lamp, was 8s. 6d. 



In answer to a question, Mr. Brown said he burnt paraffin oil in it, and 

 certainly the light it emitted was very pure and white. 



The President thanked Mr. Brown for calling their attention so ably 

 to such a useful lamp. Any one accustomed to work with the microscope must 

 at once be convinced of its great usefulness. 



He then called upon Mr. Rankin to read his paper : —
